Overview

This is page is being used to track the realization of the Hardware Platform Awareness (HPA) functional requirement defined in support of VoLTE, vCPE and 5G use cases. The requirement calls for enablement of hardware platform feature awareness (HPA) inside the ONAP management platform, or means by which knowledge about underlying compute hardware platform capabilities is exposed to VNFs running on top of the platform in order to optimize, accelerate and/or otherwise augment their execution. In ONAP, HPA enablement focuses on discovery, health monitoring and configuration of hardware platform capabilities within the NFV infrastructure, and their consumption by the virtual network functions and network services deployed on top of the infrastructure.

More Information (Intel-specific)...

Business Requirements

This requirement is required in support of commercial VNF implementations, that are used as part of vCPE, VoLTE and 5G use cases, and require hardware assisted acceleration. This requirement is also needed by the ONAP Optimization Framework (OOF) project in order to optimize homing and placement of hardware assisted VNFs.

Participating Companies

AT&T, Intel, Cloudify, China Mobile, Orange, ARM

Scope

The scope of this requirement is limited to consumption of hardware platform capabilities for the purpose of VNF performance acceleration and optimization. Other uses of HPA are not in scope.

Participating Companies

AT&T, Intel, Cloudify, China Mobile, Orange, ARM

HPA Casablanca Enhancements

Feature

Projects

Status

Notes

Support for vFW and vDNS use cases

In R2, only the vCPE SO workflow was enhanced to call OOF for homing decisions. In R3, SO workflows for vFW and vDNS will also call OOF for homing decisions.

SO

Status

colour	Green

Most of code will be in by Wednesday.

Enabled Functionality

Test plan to ensure that both vFW and vDNS use cases are tested with HPA feature

Use of Multi-Cloud Service instead of SO for direct communication with OpenStack instances in cloud regions

In R2, as part of the vCPE workflow, SO bypassed the Multi-Cloud service and called OpenStack directly.. In R3, this will no longer be the case and SO will call the Multi-Cloud Service. Multi-Cloud service will, in turn, communicate with OpenStack instances within different cloud regions.

SO
Multi-Cloud

Status

colour	Yellow

Code being integrated late on Wednesday.

Test plan should ensure that SO is configured to work with Multi-Cloud Service.

Derivation of HEAT parameters from OOF homing decisions in the Multi-Cloud Service

In R2, vCPE HEAT template parameters and their values were generated by SO, based on OOF homing decisions because SO was calling Openstack directly. In R3, communication with OpenStack is moved to the Multi-Cloud Service and SO will no longer generate HEAT template parameters. Instead, the Multi-Cloud API will accept directives from OOF and SDN-C, passed as API call parameters. Multi-Cloud service will generate HEAT template parameters based on these directives.

SO
OOF
Multi-Cloud

Status

colour	Green

Dependency on #2.

Test plan should ensure that HEAT parameters and values generated by Multi-Cloud are as expected.

SRIOV-NIC HPA feature support

SRIOV-NIC HPA feature is added in R3.

Multi-Cloud
SO

Status

colour	Green

Dependency on #2 and #3.

Test plan should ensure that OOF makes right decisions and right Openstack flavor is selected.

Cloud-region and flavor selection enhancements in OOF

In R2, OOF always selected the first cloud region to satisfy all mandatory HPA requirements, even if multiple cloud regions were able to satisfy the requirements. In R3, OOF will use scoring to pick the right cloud region, such that the region with the highest score is always chosen.

OOF

Status

colour	Green

Test plan should cover to ensure that the right region with best score is selected in case of multiple regions.

Missing E2E integration testing, can be done after M4

Support for vCPE use case

In R2, vCPE orchestration was only possible using SO and HEAT templates. In R3, vCPE orchestration will also be possible using VF-C and partially ETSI NFV SOL001 v0.6.0 compliant TOSCA templates. As part of this change, VF-C (NSLCM) will be enhanced to communicate with OOF and use OOF supplied recommendations for placement.

VF-C
SDC
Policy

Test plan should ensure that vCPE use case is tested using both VF-C and SO. In either case, the same OpenStack flavor and cloud region should be selected for VNF placement.

Casablanca Test Plan (DRAFT)

Please see this link: HPA & Cloud Agnostic Intent - R3 Test Plan (In Progress)

Assumptions

VolTE and vCPE use cases will be used to validate the function of HPA end-to-end. The HPA test plans for Casablanca make the following assumptions with respect to function of ONAP components affected by HPA enablement functional requirement.

There are no changes to the HPA capability discovery process.
There are no changes to how discovered HPA capabilities are persisted in AAI.
There are no changes to specification of HPA constraint policies used by OOF.
Existing VoLTE and vCPE tests are sufficient to perform the end-to-end HPA testing.

Based on the above assumptions, the scope of the testing effort is limited to the following:
